How It Works

1. Ohm’s Law Calculator (V = I × R)

Need to find voltage, current, or resistance? Enter any two values, and the plugin calculates the third automatically.

Example:

  • If Current (I) = 2A and Resistance (R) = 5Ω, the calculator will show:
    Voltage (V) = 10V

2. Power Law Calculator (P = V × I)

Calculate electrical power, voltage, or current by entering two known values.

Example:

  • If Voltage (V) = 12V and Current (I) = 3A, the result is:
    Power (P) = 36W

3. Resistance Calculator (R = V / I)

Find the resistance of a circuit by inputting voltage and current.

Example:

  • Voltage (V) = 9V, Current (I) = 1.5A → Resistance (R) = 6Ω

4. Current Calculator (I = V / R)

Determine current flow when voltage and resistance are known.

Example:

  • Voltage (V) = 24V, Resistance (R) = 8Ω → Current (I) = 3A
